IIRC, there was an article in a California based magazine that indicated that it was going to be a D-Ticket level attraction. I am almost certain of it because I remember the excitement that generated when it was published.
EDIT: Actually, I just googled it and one of the first links that came up calling this ride a D-Ticket level attraction is this site!
